How many grams are in 1.4 x 1023 molecules of Nickel Hydroxide (Ni(OH)2)?

gold is my favorite solid.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
